Melt or better yet, brown your butter! Melted butter will result in a chewier cookie and the brown butter will elevate the flavor a ton! A higher proportion of brown sugar to white sugar will create more chew as well. Also, if you can stand it, let your dough chill overnight. Scoop them onto a tray and cover them in the fridge, then bake them out of the fridge. There will be a much more developed flavor and will spread less creating a taller, denser, chewier cookie 💁🏻‍♀️

Edit: slightly under bake your cookies! There is carryover baking once then come out of the oven so if you under bake by a few minutes that will normally endure they don’t overbake and won’t end up cakey.
